While many fans initially presumed it was due to the manicure, or some interesting Australian twist on applause, they would be wrong. Nicole has spoken out about her strange move during an appearance on Ellen this week.

Ellen DeGeneres pressed the actress on Clapgate 2017, asking her to explain the reason she can't seem to grasp such a simple concept.

"It’s the Cinderella thing," she said. "You borrow these expensive jewels, and I’m like, ‘I must not damage these diamonds!’ 'Cause I have to give them back at midnight."

The star original spoke with Kyle & Jackie O about the strange move, during an interview in March.

"It was really awkward," she told the KIIS Radio hosts. “I was like, ‘I wanna clap, I don’t wanna not be clapping’ – that’d be worse, right? Like ‘why isn’t Nicole clapping?’ “So therefore I’m clapping but it was really difficult because I had a huge ring on that was not mine – but it was absolutely gorgeous – and I was terrified of damaging it.”
